From a9188028fd8a446413be48e7f6490f2d18a8d07e Mon Sep 17 00:00:00 2001 From: Matthew Vick Date: Tue, 28 Aug 2012 06:33:05 +0000 Subject: [PATCH] igb: Correct PTP support query from ethtool. Update ethtool_get_ts_info to not report any supported functionality on 82575 and add support for V2 Sync and V2 Delay packets. In the case where CONFIG_IGB_PTP is not defined, we should be reporting default values. v2: Correct the function to return EOPNOTSUPP when there is no PTP support or the device does not support PTP. Also fix minor whitespace issue.
